Electricity is the movement of electrons from an area of high concentration to another area of lower concentration. In a generator, a collection of wires surrounds a rotating magnet, pushing and pulling electrons back and forth through the conductive metal in wires. This is known as AC or alternating current electricity like you would find in your wall outlets. It moves in one direction and then another, alternating directions 60 times per second (or 60 hertz) in a standard USA wall outlet with 110 units of electric pressure known as volts. If the pressure is allowed to flow through the circuit, then the number of electrons passing through is measured in amps. The work produced (light, movement, heat, etc) is measured in watts (calculated as volts times amps).
If electrons are chemically stored in a battery, then the electrons will want to flow from the negative side (where there are more electrons) to the positive side (which has less electrons) in one direction. This is called DC or direct current electricity. When enough electrons have flowed from the negative to the positive and the number of electrons in both sides of the battery is equal, then there is no more pressure and no more flow, resulting in a dead battery.
